Abstract
A substance capable of devitalizing hazardous biological agents and deactivating hazardous chemical agents comprising an activated anion exchange resin having a particle size substantially in the range of about 0.1-300 microns, which resin particles have been iodinated by exposure to a sufficient amount of an iodine-substance absorbable by the anion exchange resin such that the resin particles absorb the iodine-substance so as to convert the resin particles into activated resin particles. The iodine-substance may be selected from the group consisting of I2 (i.e., diatomic iodine), and polyiodide ions having a valence of −1. The activated resin particles may be placed into contact with the biological or chemical agent as a dry aerosol, by dust coating, or by admixing the particles with a carrier to form a coating.
